Pete when I glued the strips with epoxy it did not sand at the same rate as the foam and wanted to dish between the glue and foam.
With Gorilla the dried glue it is about the same density as the foam and sands out fare. Rememeber this is a thin line of glue that may come out between the stips.
Also - if you wet the surfaces before you apply the gorilla glue, the glue will foam as it cures. More water makes it foam more.
